Amber is one of the few jewellery materials that genuinely improves with handling. The natural oils from your skin keep the resin from drying out and turning brittle, and a necklace worn regularly often looks richer than one left in a box for years. The catch is that the same softness which makes amber so pleasant against the skin also makes it easy to scratch, cloud and crack. Caring for it takes minutes rather than hours — you mainly need to know which habits to avoid.
Amber is fossilised tree resin, not a mineral. On the Mohs hardness scale it sits around 2 to 2.5, roughly the same as your fingernail and far below the quartz, sapphire or diamond used in most other jewellery. A stray grain of sand on a kitchen worktop is hard enough to leave a mark.
It is chemically sensitive too. Alcohol, acetone, ammonia, chlorine, perfume and hairspray can all attack the surface, leaving a dull, cloudy or tacky patch that will not polish out at home. Heat is the other enemy. Amber is a poor conductor and dislikes sudden temperature changes, so thermal shock can open cracks that were invisible a moment earlier.
Most amber damage is not caused by cleaning. It is caused by what the piece comes into contact with while you wear it, and a handful of small changes covers the majority of the risk:
For routine cleaning you need very little: lukewarm water, a soft cloth and, occasionally, a drop of mild unperfumed soap. Skip ultrasonic cleaners, steam cleaners, silver dips, toothpaste and bicarbonate of soda — all are too aggressive for resin.
Never use a toothbrush on carved amber, and never rub hard to shift a stubborn mark. A scratch from over-enthusiastic cleaning is permanent, and a cloudy patch left by perfume is not always fixable either, so prevention does most of the work.
Amber is happiest in a cool, dark place with a little airflow. What it dislikes is a jumbled jewellery box.
Check the length before you wear it. A necklace that rubs against a rough collar, a metal zip or a bag strap will wear at those contact points. Look at the stringing thread now and then: if beads are sliding loosely, or the thread looks frayed near the clasp, have it restrung before you lose beads. Silk or cotton thread, knotted between beads, offers the best protection, and a necklace worn constantly is usually restrung every few years.
Bracelets take more knocks than anything else in the box because they sit on the wrist. Take them off before sport, and before long sessions at a keyboard if the clasp tends to catch. Roll them on and off over a soft surface rather than stretching them — the thread, not the amber, usually fails first.
An amber ring needs a setting that protects the stone. A high claw setting leaves the edges exposed, while a bezel or rub-over setting that covers the rim is much safer for daily wear. Even then, rings are the first casualty of washing up, gardening and gym sessions, so take them off. If you are buying amber for a child, follow current safety guidance: necklaces on infants carry strangulation and choking risks and should never be left on an unsupervised or sleeping child. If you have questions about health claims made for amber, ask a qualified health professional.
Run a quick check every few months. Look at the beads at the back of a necklace, where wear is heaviest, and at the points where metal meets resin. Fine scuffs can sometimes be softened with a tiny amount of olive oil and patient buffing, but deep scratches, chips and internal cracks cannot be polished out at home; a jeweller who works with amber is the better option. Cloudiness that appears after contact with a chemical is usually permanent. Cloudiness that has always been there may simply be the character of the piece, since much Baltic amber is cloudy by nature.
Clean amber when it looks grubby rather than to a strict schedule — once every few months is plenty for most pieces. Put it on after your perfume, take it off before your shower, store it in a soft pouch away from heat and harder jewellery, and check the stringing once a year. That is the whole routine, and it is enough. Do those few things and your amber will keep the warm, honeyed glow that made you buy it, and remain wearable in twenty years' time.
